The present invention relates to anti-rattle dovetails, particularly forautomobile doors,

1 an objectbeing to provide a device of this character which willprevent the rattle usuall'y resulting from the vibration and wearing ofthe doors, eifectually retaining the saine against vertical movement andwear, and which will at the Sametime r-etain the door in apredeterminedposition against movement in a line parallel to the plane of the door,thusl preventing any rattle that may re' sult from movement and wear inthis direction. t isparticularly proposed, in theVV exemplary embodimentillustrated, to provide a device in which a socket'member is providedwith self adjustable resiliently supported `dovetail members-adapted tohave a wedge member engaged between them, the respective -dovetailmembers being supported against vertical movement, and in which there isaV diagonal interlocking engagement between the dovetail members and thewedge member forcing and retaining the latter in a fixed position in ahorizontal linetransversely of the lateral adjustment of said dovetailmembers.

With the above and Votherobjects in view embodiments of the inventionare shown in the accompanying drawing, and these embod-V iments will behereinafter more fully described with reference thereto, and the inven-Ation will .be finally pointed out in the claims.

Thecasing of the socket member .comprises y.an outer part consisting ofa face plate member 12 preferably formed of she-et metal,hav ing aflange 13atitsforward edge bent inwardly at a slightly obtuse angle,anda lip 14 bent forwardly from the flange '13; A rearwardlyconvergingopeninglis provided in the face plateand extends across theflange 13 to the lip 14, the forward portion of the openposed inparallel relation. An inwardly bent ing having its upper and loweredgesk dis- Y rim flange, 16 is formed atjthe upper and Y lower edgesofthe faceplate, land counter? sunk screw holes 17 are lprovidednear theup; per and lower edges of the plate member and the flange 14. i

The inner or boX part of the 4casing vis formed fromsheet metal andcomprises a rectangular'portion 18 having upper and lower wall flanges19 bent from the upper andlower edges,- anda rear wallflange 20 bentfrom the rear edge. Attaching ears v21 are bentoutwardly from the'wallriianges 19 andare adapted to be secured to the inner side of the faceplate 12, preferably by spot welding as at 22. The forward edges ofthewall flanges 19 are cut, as at-23, Fig. 8, to correspond to the angle ofthe flange 13 and the forward edge of the portion aq gitudinally,whichpermits firm engagement each other.

extends intol the opening 15 and abuts the edge of the flange 14, sothat said portion 18 and the flange 14 are in flush relation to eachother. o v

A pair of inwardly bent lugs arev struck from the rear wall flange 2O ofthe casing vfor supporting the ends of the springs, presently to be morefully referred to. i

' A pair of opposed'blockmembersfl 'and posed within thevcasing, theblock 26 having a flat surface 28 at its underside adjacentits* innerend .transversely inclined downward- K ly toward the portion 18 ofthe'casing, while the block 2( has a flat surface 29 atits upper sideadjacent its inner end which is parallel to and slidably engages thesurface 28, thus cooperating with the upper and lower parallel walls ofthe vcasing to prevent vertical displacement of the blocks whilepermitting them to slide" longitudinally, relatively to Inclined faces30 and 3 1 extend fromtheiiat surfaces 28 and 29 to the forward ends "ofthe blocks in diverging relation, and are transversely inclinedldownwardly in parallel relation towardthe portion 18 of the casing, thusproviding a diverging-and transversely inclined recess between theblocks. Thefaces 30 and 31 fare slightly arcuate .lon-

ofthe wedge member irrespective of slight variations inl theverticalalignment of the door. Pockets 32 .are provided inthe rear walls'of theblocks within which are engaged coill springs 33 positioned upon thelugs 25 of the casing, and which 'pressjthe blocks forwardlv against theflange 13, as shown in Fig.

1, while permitting them to be forced'later-V ally inward, as shown inFigs. 6, 7 and-'8.

The blocks may be of any suitable material, and because ofv theprotection against breakage afforded by Vt-hecasing, maybe of fibre',

bal'relite, or other suitable 'squeak preventing self-lubricatingmaterial. j

The wedge member comprises Aan attaching vbase 34 having counter" sunkscrew holes 35, and' a rigid-wedgeprojection36 having its convergingsurfaces 37 and'38 inclined from the neck-portion 39" at thebase'inparallel relation toeachy other and in substantial correspondence to thetransverse inclination ofV the recess between the bloclrs 26V and1 27.The

forward edge 40 of the wedge projection is Yslightly projected withrespectV to the neckV portion, so that it may clear the plate' '12Lof"the socket member in the engaged relation ofthewedgemember asindicatedin Fig. 8'. The operation is as followsz When the door Vis 'in openposition the blocks 26 and 27 are projected" forwardly against'the 'ange13 of the casing, si'ndicated in Fig. 1.1 VAs the door isclosed thewedge member 36 engages betwee'nthe blocks, contactingtherewith beforethe'door is completely closed, the completeclosure ofthe door causingthe blocks to be moved laterallyl against the pressure offthe springs,while the longitudinal inclination of the engaging `doom-whilethebtherblock tends to-press it 27 oflugenerally rectangular .shape aredis-" in the other direction', and the door is thus laterally and"vertically.

The door Yisprovided with the usual latch now shown, which "engagesbehind a striker on the door frame, andthe present device issuchffthatit permits the door to close sul-V ciently to allow the latchto 'operate,'and thereupon exerts an outward pressure on the door toforce the latchybolt tightly against the striker. 1 Upon release ofthelatch the device exerts an opening'pressure on the door.

Shouldthe wedge member be out of alignmentV with the socket,`dueto,sagging of the door or inaccuratemounting of the `wedge member, theindependent movement of the respective blockswill-permit them to adjustthemselves to thewedge surfaces' and perform their cooperativeretaining'function.

- While It have shown the socket member on the door frame andthe wedgemember on held in a iiXed predetermined position, both f tion, but itwill be obviousthat changes may be 'made therein, within the spirit andscope thereof, as defined-iny the appended claims. Having thusdescribed. my invention what I: claim and desire to-secure by LettersPatent is Y.
